Evaluating Functions

Front

What is a function?

Back

A function is a relation that assigns exactly one output for each input from a set of inputs.

Front

How do you denote a function?

Back

Functions are typically denoted by letters such as f, g, or h, followed by the input variable in parentheses, e.g., f(x).

Front

What does f(2) represent?

Back

f(2) represents the output of the function f when the input is 2.

Front

How do you evaluate a function at a specific point?

Back

To evaluate a function at a specific point, substitute the input value into the function's equation.

Front

What is function notation?

Back

Function notation is a way to represent functions using symbols, typically in the form f(x) = expression.

Front

How do you read f(x)?

Back

f(x) is read as 'f of x'.

Front

What is the output of f(x) = 2x - 3 when x = 4?

Back

f(4) = 2(4) - 3 = 8 - 3 = 5.

Front

If f(x) = x + 3, what is f(-2)?

Back

f(-2) = -2 + 3 = 1.

Front

Translate the coordinate pair (0, 8) into function notation.

Back

f(0) = 8.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.
